Microsoft has been running its Bing search service for a few years now and today the company got some good news. The Associated Press (via USA Today) reports that for the first time since Bing launched in June 2009 it reached the number two spot in the US for Internet search results.

The information comes from Comscore which said that in December Bing and Microsoft's other websites had 2.75 billion search requests in the US. That amount gave Bing and Microsoft 15.1 percent of all the search traffic in the US that month. Yahoo, the long time number two search engine, went down in December to the number three spot with 2.65 billion search requests in the US or 14.5 percent of US search traffic.

Naturally Google still dominates as the number one search engine in the US. Comscore said that in December it had 12 billion US requests or 65.9 percent of the search market.

Microsoft is still in the middle of a 10 year deal with Yahoo to provide the majority of the web site's search technology. If you combine Microsoft's numbers with Yahoo it means that Microsoft's search engine technology now controls 29.6 percent of US search results.
